FOLDING LUNCH-Box.

4 Specification of Letters Patent.

Patented June 25, 1907.

Application filed January 20, 1905. Serial No. 241,996:

To a/ZZ whom t may concern,.-

Be it known that I, MYRON A. GILMAN, a citizen of the UnitedStates of America, and a resident of Westfield, in the county of Hampden and State of Massachusetts, have invented certain new and useful Improvements in Folding Lunch-Boxes, of which the following is a full, clear7 and exact description. v

This invention relates to improvements in lunch boxes of the kind made from semirigid material, such as millboard, and so constructed as to be either set up to constitute a lunch carrying receptacle, or to be collapsed and folded to be easily carried in a pocket.

The principal object of this invention is to 1 produce a folding lunch box which by reason of its construction, and the formation of its component parts, may be most cheaply made and with the utmost economyT of stock. Another object of the invention isto provide a folding lunch box, which, when set up and in use, is entirelytight and inclosed. And further objects and advantages in this improved folding lunch box are found to be attained in and by the forms constructions and relative arrangements and combinations of the parts shown and described.

The improved lunch box is illustrated in the accompanying drawings, in which,

Figure l is a perspective view of the box set up,-the part at one end being shown as broken out, and in partial section for clearer illustration. Fig. 2 is a'perspective view of.

the folded and partially flattened lunch box. Fig. 3 is a central longitudinal vertical section, and Fig. 4 is a vertical cross section, of the lunch box. Fig. 5 is a perspective view showing the components of the box made of two blanks as in separated relations. Figs. 6 and 7 are plan views of the complementa] blanks, which together constitute one of the improved Jfolding lunch boxes.

Similar characters of reference "indicate corresponding parts in all of the views. l

In the drawings, the folding box is shown as composed of opposite side sections A and B, and opposite end sections C C, as continuations of the ends of the front side section A, and having connection with the opposite, rear, side section B and bent angularly to, and extending from one to the other of, the side sections and the end sections C C are constructed by the central vertical creases or' scorings a to be foldable and collapsible inv the manner and relatively to the other parts, as epresented in Figs. 2 and 5 more particular y.

One of the side sections, in the present instance the front one A, has, as a transverse right angular and foldable extension thereof, a bottom constituting section D, which at its opposite ends has, as continuations thereof, the spreader iiaps E E of dimensions to closely fit against the end walls of the box. The other side section,the one which is here represented by B, and which is end Wise connected with the box end sections has, as a transverse and angularly bent extension of, and along its entire lower edge, the secondary bottom iiap or section F, the width of which is preferably as great as the internal transverse dimensions of the box,-although not necessarily so wide and it will be seen with reference more especially to Fig. 4, in what manner a long slit-like opening at the bottom right hand corner of the box is eifectually closed.

One of the box side sections, here the rear one B, is shown as having as a transverse angularly bent and foldable extension, the

cover G, which in turn is provided, by preference, .and for advantage with the comparatively narrow opposite end tongues or iiaps d d, and the front or free edge tongue or flapf.

This folding box having in the material from which it is composed, creasings or ssorings, as' represented by the dotted lines on the plan views of the blanks, and as easily apparent in the perspective views, in setting up the collapsed box to bring it to condition for the rece tion of its contents, the opposite sides heid vertically are first drawn apart, distending the centrally creased end sections C C 3 the bottom section D is next swung down to its place horizontally at the base of l the box carrying therewith the spreader flaps E E, which lare next swung up against the collapsible end sections C C, and as common for the function of spreaders in this general class of boxes, these flaps E E prevent the collapsing of the front and rear sides; and the spreader flaps also, by the close character of their continuous and hinge-like connections with the bottom roper D, form closures for the bottom end) corners of the box, which would in the absence of these parts, have l.transverse slit-like openings or cracks; the supplemental or secondary bottom ilapis next swung down to placer-and, of course, only after the spreaders have been IOO upswung to their places, and then the cover is, or may be, swung down on the top of the box, its narrow end flaps or tongues d d interleaving between the end wall sections C C, and the spreaders E E, while the front flap f of the cover laps down beyond the upper edge of the box to be fastened, any description of fastening device being provided at g.

In Figs. 1 and 4, the secondary bottom flap F is shown as having a tab or loop 7L, so that when desired to swing the flap f against the back side, preparatory to folding up the box, the upswlnging of the said flap F may be conveniently performed.

J represents a strap or tape for carrying the box, the same having, by its one end, a permanent fastening represented at 'i at one end of the box, and a detachable fastening, represented at jz, at the other end of the box,-the locations of the fastening at the opposite ends of the box ybeing referably such that the strap has a slightly iagonal or oblique traverse over the top of the box, as represented in Fig. l.

Inasmuch as it is most practicable in the makeup of this box to construct it of two blanks made with no waste asvto the one shown in Fig. 7, and with a minimum of waste as to the one shown in Fig. 6, the blank shown in Fig. 6 and which comprises as an entirety the side section B, the secondary bottom flap F, and cover G with the flaps or tongues d d and f-is made with the stay sections m m as narrow endwise continuations of the side section B, which in setting up the box are bent angularly to the rear side section B and lapped against the` rear edgewise portion of the end sections C C and secured thereto by any suitable means either by gluing, or as shown by the employment of .metallic fastenings n. And it is apparent that the rectangular blank shown in Fig. 7 having the scorings represented by `the broken lines and the longitudinal slits extending centrally and from the opposite ends toward the middle ofthe blank, constitutes in a most simple manner, and as an entirety the side and end sections A, C C, the bottom proper D, and the spreader flaps E E, and it will be pointed out that the creasings or scorings t t at the junction of the spreader flaps with the bottom D, are slightly inwardly offset from the creasings or scorings u u so as to let the bottom section have its proper movements and disposition within the rectangular space inelosed by the box walls without buckling, and also enabling, with the freedom desired, the appropriate movements of the spreader iiaps.

Having thus described my invention, what I claim and desire to secure by Letters Patent is 1. A rectangular folding lunch-box essentially composed of opposite side-sections, and opposite end sections permanently connected with, and extending between, the side sections, and foldable vertically at their middle portions, a bottom section hinge-connected with and extended from the lower edge of, and foldable relatively to, one of the side sections, and having spreader flaps at its opposite ends, foldable against the saidv end sections, and also against the said bottom section, a secondary bottom section hinge connected to the lower edge of the side section opposite the one to which said. first named bottom section is foldably hinged, and foldable against the side section to which it is connected, and adapted, when the box is set up, to overlie the first named bottom section inside of the said spreader flaps,-one of the side sections having a cover section hingeconnected, and foldable relatively, thereto.

2. A folding box consisting of two blanks of semi-rigid material, one of said blanks comprising a side section A, and as opposite end continuations thereof, the end sections with creases centrally, and from top to bottom, thereof, and said side section having transverselytherebeyond a bottom section D which is provided at the opposite ends thereof with spreader flaps which are foldable against said bottom section, and said bottom section with such spreader flaps being foldable against the side section A; and the other of said blanks comprising the side section B having at the ends thereof stay sections, and having in sidewise extension thereof a secondary bottom flap F which may overlie the other bottom section D, and also be folded against the side section B, the said stay sections being folded to lap beyond the vertical edges of the end sections of the blank A, and means connecting the stay sections and end sections.

Signed by me at Springfield, Mass., in presence of two subscribing witnesses.
